Reduced graphene oxide synthesis by hummer method

Abstract

In this study, Graphite Oxide (GO) film with a 2-D structure was successfully synthesized via the Hummer method. The GO film was further reduced by hydrazine to form a few layers of graphene. The graphite oxide and reduced graphene oxide synthesized in this study were characterized by Scanning Electron Microscopy (SEM), Raman spectroscopy, and XRD analysis. A low-cost method using simple chemicals was employed to synthesize GO films with high conductivity on a large scale. The synthesized reduced graphene oxide can serve as an excellent material for various applications due to its lower cost and higher thermal, mechanical, and electrical conductivity. Large surface area graphene-based sensors and solar cells can efficiently replace expensive Carbon Nanotubes (CNTs).
